Apple Inc's fiscal first-quarter earnings reveal that the company's struggles in China and in its critical iPhone business will continue, while analysts say the tech bellwether could reduce prices to remedy the situation.

On Jan 29, Apple said revenue for the three months ended Dec 29 was $84.3 billion, off 5 percent from a year earlier. Profit was $19.9 billion or $4.18 a share.

The US tech giant said revenue from iPhones declined 15 percent from the year-earlier period. In China, Apple reported revenue of $13.1 billion, down sharply from $17.9 billion the earlier year.

Apple investors have been worried about sales in China since the company last month lowered guidance for the quarter due to economic pressures in the region and weak iPhone sales. CEO Tim Cook also blamed trade tensions between the United States and China for the slowdown in sales.

"Apple and Cook face one of their most challenging growth periods in the company's history with weak iPhone sales in China being the 'albatross around its neck' showing no signs of abating over the next few quarters, a dynamic that will be an overhang on the stock for the next six to nine months with the China trade talks adding to the agita for investors," Wedbush Securities analysts Daniel Ives and Strecker Backe wrote in a research note.

Strategy Analytics, a global consulting firm, said Apple has an Asia problem, particularly in China.

"China is Apple's second most important market, after the US. China accounts for three in 10 of all smartphones sold worldwide, and it is a market Apple simply cannot ignore," Neil Mawston of Strategy Analytics told China Daily.

Ives and Backe said Apple needs to consider an iPhone-price cut in China. "Apple is facing a 'code red' situation in China, and the right pricing strategy around XR and future versions will be key to putting a ring fence around the core installed base in the region.

"With lower-priced competition from all directions with Huawei and Xiaomi front and center, Apple needs to make sure that over the next few quarters they do not lose any current iPhone customers," they said.

Mawston said the iPhone has been struggling in China for the past three years after major carriers like China Telecom reduced their subsidy programs for 4G smartphones. "De-subsidization has made the iPhone look much more expensive at the point of sale in China, causing iPhone demand to crash," he said.

Apple can reignite demand for the iPhone by cutting prices, introducing a much cheaper model, or persuading carriers like China Telecom to restart their subsidy programs, added Mawston.

Apple said its services division, which includes iCloud, the App Store and Apple Pay, saw revenue advance to $10.9 billion, up 19 percent over the prior year. The company said China's move to pause approving new games for the App Store last year is affecting revenue in the segment.

Apple still relies on China to produce many of its products, so it will be watching the trade negotiations between China and the US closely.

Mawston said it is highly unlikely Apple will move any iPhone production to the US.
